Maths cubes are generally interlocking plastic cubes, brightly coloured that are used to show odd/even numbers, patterns, graphs, place value, addition, subtraction and multiplication. There are many other ideas too for using interlocking maths multilink cubes and these can be found on activity cards or in a super Unifix/Snap cubes book. Also available are cube activity boards that are gridded perfectly for 2cm cubes.
